Description

Technical Field

[0001] This utility model relates to the technical field of tempered glass processing equipment, and in particular to a tempered glass unloading device. Background Technology

[0002] Tempered glass is a type of safety glass with high mechanical strength and good thermal stability. Its production process typically involves heating ordinary glass to near its softening point, followed by rapid and uniform cooling. This creates compressive stress on the glass surface and tensile stress internally, thereby increasing its strength. After heating, the glass needs to be quickly and smoothly transferred from the tempering furnace to a cooling station for air-cooling quenching. The smoothness and efficiency of this transfer process directly affect the tempering quality, yield, and production efficiency. In existing technologies, common furnace exit devices often employ roller conveyor mechanisms made of high-temperature resistant metal materials. These mechanisms typically use a motor to drive a series of parallel rollers, utilizing the friction between the rollers and the lower surface of the glass to transport the glass from inside the furnace to outside. The existing technology has the following problems: In existing technologies, tempered glass lacks an effective positioning and correction mechanism during the conveying process after being unloaded from the furnace. The glass is prone to deviation or off-tracking on the roller conveyor, resulting in uneven tempering, edge collision damage, or reduced yield, affecting production efficiency and product quality. In existing technologies, glass fragments, dust, and other impurities easily adhere to the surface of the conveying rollers, and there is a lack of automatic cleaning function. The accumulation of fragments may scratch the glass surface or increase the conveying resistance, resulting in unstable glass conveying, increased surface defects, and inconvenient cleaning and maintenance, affecting the long-term operational reliability of the equipment.

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] like Figure 1-5 As shown, this utility model provides a tempered glass unloading device, including a U-shaped unloading channel plate 1. The U-shaped unloading channel plate 1 constitutes the main support and conveying channel frame of the device. Between the two vertical side walls of the U-shaped unloading channel plate 1, several parallel tempered glass conveying rollers 11 are movably installed through bearings and other components. These conveying rollers together constitute the roller channel for conveying glass. To drive all tempered glass conveying rollers 11 to rotate synchronously, a drive mechanism 2 is provided on the left side of the U-shaped outlet channel plate 1. Specifically, the drive mechanism 2 includes a drive box 21 fixedly installed on the left side of the U-shaped outlet channel plate 1. Several sprockets 22 are evenly installed on the right side of the inner wall of the drive box 21 through bearing seats. The left ends of several tempered glass conveying rollers 11 pass through the left side wall of the U-shaped outlet channel plate 1, extend into the inner cavity of the drive box 21, and are fixedly connected to the right side of the corresponding sprocket 22. A chain 23 is installed on the outer wall of all sprockets 22 through meshing. A servo motor 24 is fixedly installed at the front left side of the drive box 21. The output shaft of the servo motor 24 is fixedly connected to the left side of any one of the sprockets 22. When the servo motor 24 is started, it drives the chain 23 through the sprocket 22, thereby driving all sprockets 22 to rotate synchronously, and finally realizes the synchronous rotation of all tempered glass conveying rollers 11, providing stable conveying power for the glass. At the front end of the U-shaped outlet channel plate 1, i.e. the glass output end, there is a receiving plate 3, which is used to receive and transfer the tempered glass sent out from the conveyor roller and guide it to the next process.

[0017] like Figure 1-5As shown, in order to correct and position the glass during the conveying process and prevent it from deviating, a glass positioning mechanism 4 is provided on the outside of several tempered glass conveying rollers 11. The glass positioning mechanism 4 mainly includes a positioning control box 41, a servo motor 43, a positive and negative threaded rod 44, a moving plate 46, and a positioning conveying mechanism 47. The positioning control box 41 is fixedly installed on the front side of the top of the horizontal platform surface of the U-shaped furnace outlet channel plate 1. A moving groove 42 extending in the left and right direction is opened on the rear side of the positioning control box 41. The servo motor 43 is fixedly installed on the left side of the positioning control box 41, and its output axis extends to the right, penetrates into the inner cavity of the moving groove 42, and a positive and negative threaded rod 44 is fixedly installed at the end. The positive and negative threaded rod 44 is supported on the inner wall of the moving groove 42 by bearings and can rotate freely. The left and right sides of the outer wall of the positive and negative threaded rod 44 are respectively machined with threaded walls with opposite directions of rotation. The two moving plates 46 are respectively threadedly connected to the corresponding threaded walls on the positive and negative threaded rod 44 through their threaded holes. Preferably, a limiting slide bar 45 is fixedly installed between the left and right sides of the inner wall of the moving groove 42. The two moving plates 46 are simultaneously slidably sleeved on the limiting slide bar 45. In this way, when the servo motor 43 drives the positive and negative threaded rod 44 to rotate, the two moving plates 46 will move synchronously towards or away from each other along the moving groove 42 under the limiting action of the limiting slide bar 45. The rear ends of the two movable plates 46 are respectively connected to a set of positioning and conveying mechanisms 47, and the two sets of mechanisms are arranged in a left-right mirror symmetrical arrangement. Each set of positioning and conveying mechanisms 47 includes a translation positioning plate 471. The translation positioning plate 471 is evenly provided with a number of through circular holes 472. The number and spacing of the circular holes 472 correspond to the tempered glass conveying roller 11, so that the translation positioning plate 471 can cover the conveying roller. That is, the upper part of each tempered glass conveying roller 11 passes through a corresponding circular hole 472. In the inner circle of each circular hole 472, a number of steel balls, such as ceramic or high-temperature resistant steel balls, are embedded and rotatably installed in a ring array. The inner side of these steel balls is in contact with the outer wall of the tempered glass conveying roller 11 through which they pass. This structure allows the translation positioning plate 471 to be translated and adjusted left and right relative to the stationary or rotating tempered glass conveying roller 11. At the same time, the rolling friction of the steel balls reduces the movement resistance. Above the opposite surfaces of the two translation positioning plates 471, i.e., facing the glass side, there are horizontal grooves 473. At the bottom of the horizontal grooves 473, several vertical rods 474 are evenly mounted along their length by short shafts and other components. When the glass is conveyed on the tempered glass conveying roller 11, its two sides contact the vertical rods 474 on the two translation positioning plates 471 respectively. The vertical rods 474 can rotate freely, thereby limiting the left and right position of the glass and playing a positioning role, while allowing the glass to be conveyed forward smoothly, avoiding large sliding friction between the glass side and the positioning mechanism and scratches. To further improve the stability of the translation positioning plate 471 during movement, a stabilizing slide rod 12 is fixedly connected to the rear side between the two opposing vertical sidewalls of the U-shaped furnace outlet channel plate 1, and the rear ends of the two translation positioning plates 471 are slidably connected to this stabilizing slide rod 12 respectively.

[0018] like Figure 1-5 As shown, the device also includes a cleaning and collection system. Between the two opposing vertical sidewalls of the U-shaped outlet channel plate 1, below the tempered glass conveying roller 11, several connecting rods 13 are uniformly fixedly installed. A cleaning scraper 131 is fixedly installed at the top of each connecting rod 13. The top of the cleaning scraper 131 contacts the outer circumferential surface of the bottom of the corresponding upper tempered glass conveying roller 11 with a certain contact force. When the tempered glass conveying roller 11 rotates, glass fragments, dust, and other impurities adhering to its surface are scraped off and fall off by the cleaning scraper 131. At the bottom of the translation positioning plate 471, corresponding to the inner ring position of each circular hole 472, a through hole 475 is provided, penetrating to the inner ring of the circular hole 472. This through hole 475 extends left and right, providing a downward falling channel for the scraped fragments. Above the horizontal platform of the U-shaped furnace outlet channel plate 1, below several connecting rods 13 and in front of the positioning control box 41, a debris collection drawer 14 is provided in a pull-out manner. The debris collection drawer 14 is used to collect debris and impurities falling from the through hole 475. A pull handle 141 is fixedly installed on the rear side of the debris collection drawer 14 to facilitate periodic pulling out of the drawer for cleaning.

[0019] The working principle of this tempered glass unloading device will be explained in detail below.

[0020] like Figure 1-5As shown, when using this tempered glass unloading device, firstly, according to the width of the tempered glass to be conveyed, the servo motor 2 43 drives the positive and negative threaded rods 44 to rotate, causing the two moving plates 46 and their rear positioning conveying mechanisms 47 to move towards or away from each other, thereby adjusting the distance between the uprights 474 on the two translational positioning plates 471 to be slightly larger than the width of the glass, forming a suitable guide channel; then, the servo motor 1 24 is started, and all the tempered glass conveying rollers 11 are driven to rotate synchronously through the chain 23. The high-temperature tempered glass from the tempering furnace is placed on the rotating tempered glass conveying rollers 11 and conveyed forward under the action of friction. During the conveying process, the two sides of the glass respectively contact the two... The vertical roller 474 on the translation positioning plate 471 contacts the glass. If the glass deviates, its side will press against one of the vertical rollers 474. However, since the vertical roller 474 is rotatable and the entire positioning mechanism provides lateral limit, it can effectively correct the position of the glass and ensure that it moves steadily in a straight line until it enters the next process through the receiving plate 3. During the conveying process, the surface of the continuously rotating tempered glass conveying roller 11 is constantly scraped by the cleaning scraper 131. The removed debris falls into the debris collection drawer 14 below through the through hole 475 at the bottom of the translation positioning plate 471. The accumulated debris can be cleaned by periodically pulling out the debris collection drawer 14, keeping the equipment clean and preventing debris from affecting the conveying or damaging the glass.
